  • Publication number: 20230173448
    Abstract: A method for the conversion of a carbonaceous material. The method comprising the steps of providing a carbonaceous material, providing a hot powder material and contacting the carbonaceous material and the powder material in an atmosphere configured to no more than partially oxidize carbon to CO2. The carbonaceous material is at least a partial converted into volatiles. The volatiles are separated from the additional components by specific gravity.

  • Patent number: 8894410
    Abstract: A cooler for cooling hot particulate material which has been subjected to heat treatment in an industrial kiln such as a rotary kiln for manufacturing cement clinker, includes a grate for receiving and supporting hot material from the kiln, at least one cooling gas duct which is connected to slots in the grate for introducing cooling gases into the hot material and a compressed air system for injecting compressed air into the material on the grate. The cooler also comprises at least one flow restricting device provided in the cooling gas duct. Use of the one or more flow restricting devices may permit only a very limited amount of the compressed air that is injected into the material on the grate to pass through the cooling gas duct.

  • Patent number: 7255123
    Abstract: The invention Described is a device (1) for dividing a stream of particulate or pulverulent material into at least two substreams. The device has a housing (2) with a substantially vertical inlet duct (3) and two or more outlet ducts (4, 5, 6, 7) emanating from separate openings, and being separated by partition walls (9) extending radially relative to the centreline of the inlet duct (3). The device also has a rotor 11) which is located in immediate extension of the inlet duct (3), with its axis of rotation coinciding with the centreline (10) of the inlet duct. The rotor (11) has a radially configured surface (11a) for directing the falling material stream radially outwards into the free space (12) above the outlet ducts. The device is peculiar in that the radial partition walls (9) can be adjusted in the circumferential direction. The result will be a freely variable ratio between an arbitrary number of outlet substreams.
